Music for setting up speakers



Im setting up my 30yr old Martin Logan Sequel II’s. I followed some ML guidelines and it was pretty straight forward. They are 8’ apart and 8’ from me. I towed them in using a flashlight and beam reflection, it was pretty easy, same for the reflection to be sure one isnt tilted forward or backward more than the other.

I’ve been listening to some Tidal tracks and wondering what you listen to to confirm your setup is right for you.

I listened to some solo violin and cello, some folky vocals, some Led Zepp just because :0)

maybe music where instruments are easily located ect

Thanx

I like to use mono tracks to setup speaker positions. 
Have great japanese 80's reissue of Eddie "Lockjaw" Davis Introduction to Modern Jazz.
Headhead, that 1st Hot Tuna album is great. Always one of my favorites. A system  set up right puts you there in the club. 
     Whenever speaker set-up, imaging or soundstage are mentioned, I like to remind people about these resources: The following provide tests, with which one may determine whether their system actually images, or reproduces a soundstage, as recorded.  

      Of course: no one is going to be listening to tests, etc.  BUT: it IS good to use these, to eliminate any variables, when making initial set-ups.
     
      ie: On the Chesky sampler/test CD; David explains in detail, his position on the stage and distance from the mics, as he strikes a tambourine(Depth Test).

      The LEDR test tells what to expect, if your system performs well, before each segment.

       The Chesky CD contains a number of tests, in addition to the LEDR.
